Fatigue while driving significantly impairs a driver’s ability to assess their surroundings accurately. One of the most critical effects of fatigue is the misjudgment of speed and distance. When a driver is tired, their cognitive processes slow down, leading to difficulties in perceiving how fast they are going or how far away an object or another vehicle is. This impaired judgment can cause dangerous situations, as the driver may not be able to react appropriately to changes in traffic or road conditions. Maintaining accurate speed and distance perception is vital for safe driving, as it affects how well a driver can make timely decisions, such as when to stop or change lanes.
